- Description: With ever increasing important expectations being placed on professional sportsmen and women and, with the main emphasis on winning at all costs, the role of how vision can contribute to sports performance has been under the spotlight in the last few decades. While sport vision programmes can potentially play a vital role in improving sports performance, the efficacy of visual skills training on performance, however, has not been convincingly demonstrated and therefore is still debatable. The primary aim of this study was to investigate the effectiveness of a web-based visual skills training programme on the visual skills performance of NMU Varsity Cup rugby players. The specific visual skills included accommodation, saccadic eye movement, reaction time and peripheral awareness. The study was quasi-experimental in nature and utilized a quantitative approach. A total number of 23 participants that met the inclusion criteria were included in the study by means of purposive sampling. Optometric assessments, on the advice of an optometrist, were conducted to ensure “normal” vision among the participants included in the study. A systematic procedure was employed based on the pre-test to allocate the 23 participants to either a control group (CG) (n=8), an experimental group one (EG1) (n=9) and an experimental group two (EG2) (n=6). The two experimental groups underwent four weeks of visual skills training with the EG1 receiving the web-based visual skills training and EG2 receiving the dynamic visual skills training. The tests used consisted of the Hart Near Far Rock Chart, a Saccadic eye movement chart, simple reaction time and choice reaction time as well as the Batak Pro (Accumulator test). Pre- and post-test scores showed some differences but no statistically significant (p<0.05) differences were found between the three groups for any of the tests conducted. Overall the experimental groups produced larger (non-significant) either pre- to post-test mean differences or post-test results than the control group for six of the seven tests implemented. The findings of this study using a web-based visual skills training programme presented no statistically significant improvements nor better results than the dynamic visual skill training programme in respect of visual skill performance of NMU Varsity rugby players.

- Description: The South African automotive industry has experienced significant growth since its first inception in 1995. South Africa’s trade relations with other countries has facilitated the growth of this sector. Government introduced programmes that encouraged growth in the sector, namely the Motor Industry Development Programme (MIDP) and the Automotive Production and Development Programme (APDP). South Africa as the catalyst for development in Africa needs to continuously strive to integrate with other developed countries to and promote Foreign Direct Investments into the continent. The development of the industry requires organic growth to ensure that it remains sustainable. The research problem addressed in this study is to establish the role government plays in ensuring a sustained growth of Foreign Direct Investment (FDI) in the automotive sector. The establishment of this statement is imperative to the growth of automotive investments by multinationals in South Africa. Original Equipment Manufacturers (OEM) are positioned in three of the country’s eleven provinces. The Eastern Cape region has been known to be the automotive-hub of South Africa with a GDP that is driven by the secondary automotive sector consisting of multinational OEM giants such as Volkswagen South Africa (VWSA), General Motors South Africa (GMSA), Ford Motor Company, FAW and Daimler. South African OEMs are required to lobby at the principal companies before a new model can be built in the country. Lobbying involves offering competitive logistics costs to build models in South Africa. Stakeholders led by government are required to actively participate in these negotiations to sustain the industry in the country. One of the ways this can be achieved is through formulation, integration and alignment of strategies between all stakeholders. Stakeholders involve private sector and public sector working together. South Africa has achieved an open-country perception to foreign investors through the APDP. The problem statement was accurately explained and expressed clearly and sub-problems were identified from areas in the main problem that required further analysis. Literature has revealed that South African ports are considered to be the most expensive in the world and that there is a lack of port and rail integrated infrastructure. Providing a complete supply chain for logistics will result in increased FDI for South Africa. The governmental entities’ support will allow the OEMs an opportunity to increase investment in South Africa thus creating employment and adding value to the GDP of South Africa. The South African component manufacturer’s sector has grown intensively creating sustainable jobs for South Africans. The industry is structured in such a way that there is a multiplier-effect reaction to macro-economic conditions. A comprehensive literature review was executed to understand the nature and extent of the global automotive industry, the South African automotive industry, the regions that host OEMs, the Motor Industry Development Programme and the Automotive Production and Development Programme. A primary research instrument was constructed, in the form of a questionnaire, to test themes which were highlighted in the literature review which can influence the sector’s competitive advantage. A questionnaire was distributed with the assistance of industry representatives in the Transport and Logistics sector. There was consensus on many issues regarding the current structure of the South African automotive industry. Specifically, the importance of rail, efficiencies, prices and value-added services needed in the industry to attract FDIs as well as the readiness of the Port of Port Elizabeth with regards to being positioned as an automotive-hub for Sub-Saharan Africa.

- Description: Research in the field of attachment theory and object relations theory has indicated that early attachments between a child and his or her primary caregiver have significant implications for the development of that child. Early relationships begin to shape the child’s sense of self and other and healthy relationships lead to secure attachments. However, children who encounter early maltreatment or a disruption in caregivers are particularly vulnerable to developing insecure attachments and a disrupted sense of self and other, which has consequences for their subsequent psychological development. In the South African context, increasing numbers of children are being orphaned or placed in formal foster care with many children at risk for insecure attachments. This has implications for therapeutic work with an increased need to promote secure attachment relationships and a stable sense of self and other. The current case study aimed to describe the relational experience of play therapy that took place between a maltreated five year old female child and a female trainee therapist with this purpose in mind. The therapeutic process was embedded within a relational therapy framework which included object relations and attachment theory. The researcher made use of a qualitative descriptive dialogic research approach to conduct the research. The data were analysed using content analysis, where the play therapy sessions were analysed according to concepts relating to Fairbairn’s (1963) object relations theory as well as Winnicott’s (1965) object relations theory. Prominent themes that emerged included the role of the holding environment, splitting of good and bad objects and the presence of a false self versus a true self. In addition, the conflicting presence of two repressed ego structures, namely the libidinal and antilibidinal ego structure were noted throughout the therapeutic process.

- Description: The effectiveness of harvesting slash treatments are questionable when wild fires, fuelled by post harvesting slash, burn out of control. In order to quantify effectiveness of various slash treatments, fire behaviour in Pinus patula and Eucalyptus macarthurii compartments in the Highveld area (Piet Retief) of Mpumalanga, South Africa, were assessed after application of five different post-harvesting slash treatments. Treatments included mulching, chopper rolling, windrowing, removal of slash (inter-windrowing) and broadcasting. Independent fuel and environmental variables were measured prior and during application of fire to the study areas and effects on fire behaviour were compared afterwards. Dependant fire behaviour variables such as the rate of spread, fire temperature and flame height were measured in respective slash treatment plots and compared. Results of the study indicated that fire behaviour assessed in mulched areas in both the P. patula and E. macarthurii compartments were significantly less intense when compared to fire behaviour in chopper roll, broadcast and windrow treatments. Fire behaviour in mulched plots compared favourably with areas where harvesting slash was removed (inter-windrow treatment). Comparisons between fuel loads of different treatments also indicated accelerated mineralization of organic material in mulched areas. Mulching of harvesting slash seems to be an effective method to restrict fire behaviour in post-harvesting compartments and should be considered as part of a fire management strategy.
